Thiosulphate hydrochloric acid coursework

The chemical reaction for this experiment is: If you are confident and chosen the VARIABLE you want to investigate you should try to make a quantative prediction and maybe justify it with some theory if you can. The rate of reaction i.

Sodium Thiosulphate Coursework Essay

When pouring the acid, make sure it is done above eye level. A calculator to work out the average reaction rate. Use smooth 'best curves' for as many of the points as possible, though some parts of the graph might be linear, watch out for the 'scatter' - the experiment is not that easy to get good results.

We will write a custom essay sample on Sodium Thiosulphate Coursework Order now More Essay Examples on Similarly the use of a catalyst complicates things, and if used incorrectly could alter the outcome of the experiment. I thought that the higher the concentration that we used, the test was going to be a lot quicker but the lower the concentration, the test Chemistry Rates of Reaction Coursework words - 22 pages Meter 10 Gas Collection 10 Strand Eb 11 Data Analysis 11 Graph Evaluation 11 Strand Ra 12 Secondary Data 1 12 Secondary Data 2 13 Secondary Data 3 14 Strand Rb 15 Conclusion 15 Bibliography 16 Strand Sa The Science In the experiment, I will be testing how increasing the concentration of the reactant affects the rate of reaction between hydrochloric acid and sodium thiosulfate.

Impurities in the reactants can impact the rate of reactions and inaccurate clip periods. Each enzyme has a temperature and pH level at which its activity is greatest and the reaction it catalyses proceeds at its fastest rate.

It would also be preferable to wear a scientific apron, however this is not essential. If the volume is different, then it could give different results to if it was at a constant volume.

When the temperature is being varied a water bath will be used to heat up the acid and theosophical to the necessary temperature.

The activation energy for a given reaction can be marked on the distribution curve. At the terminal of this experiment, it can be concluded that the concentration does hold an consequence on the clip taken for the reaction and accordingly on the rate of reaction. We had to add the Sodium Thiosulphate and the water at the same time for this to be a fair test also.

This means that both graphs drawn up in my analysis will have positive correlation, and will probably be curved as the increase in rate of reaction ill not be exactly the same as the counterrevolutionaries is increased. The graph above corresponds to our hypothesis as the relation between the rate of reaction and the concentration of reactants is relative to the concentration of one peculiar reactant.

Reaction between hydrochloric acid and sodium thiosulphate test?

Always wash your hands after doing an experiment, especially ones with irritant. Although Maxwell-Balletomane distribution curves are for the particles in a gas, the same distributions can be used for the particles in a liquid or solid.

This can be Justified by relating to the collision theory. The factors to discuss might be: Collisions between reacting particles are therefore more likely to occur. Only particles with enough energy to overcome the barrier will react after colliding.
